Answer:
y=3x-2
Step-by-step explanation:
your question didn't have any instructions so this might not be what you're looking for
set them equal to each other
-3x+4=3x-2
-3x-3x=-2-4
-6x=-6
x=1
plug in x=1
y=3(1)+4 =7
y=3(1)-2 =1
so, when x=1, y=1 in the expression y=3x-2
Answer:
10000
Step-by-step explanation:
4^2 (100) = 1600
so,
10^2 (100) gives us our answer of 10000
Y - 4x = 7...y = 4x + 7
now sub 4x + 7 in for y in the other equation
2y + 4x = 2
2(4x + 7) + 4x = 2
8x + 14 + 4x = 2
12x = 2 - 14
12x = - 12
x = -1
y - 4x = 7
y - 4(-1) = 7
y + 4 = 7
y = 7 - 4
y = 3
solution is : (-1,3)
Answer:
Rose bought 14 packages of granola bars.
Step-by-step explanation:
Total bill = 1 bag of potatoes + x amount of packages of granola bars
Total bill = $74.25
1 bag of potatoes = $6.00
1 package of granola bar = 5.25
We set the equation to:
74.25 = 6.00 + 5.25x
Subtract 6.00 from both sides:
68.25 = 5.25x
Divide both sides by 5.25 to leave x by itself
68.25/5.25 = 5.25x/5.25
13 = x
This means Rose bought 13 packages of granola bars.
Let's recheck our work by inputting x = 13 into the equation:
74.25 = 6.00 + 5.25(13)
74.25 = 6.00 + 68.25
74.25 = 74.25
